PDF (Portable Document Format) preserves layout exactly the same on every device, which makes it the standard for sharing documents, invoices, manuals and e-books.
Typical use: Convert to PDF when you need a fixed, print-ready layout that looks identical everywhere and cannot be accidentally reflowed or edited.
About the PDF format
PDF (Adobe, 1993; ISO 32000 since 2008) exists for one promise: the document looks identical everywhere, forever. Fonts get embedded, layout is fixed to the point, and a contract printed from a 2003 file renders the same as one created this morning. That fixed-layout guarantee made it the standard for invoices, manuals, forms, e-books and anything with legal or financial weight.
The same design is what makes PDFs stubborn. They are meant to be presented, not edited — text lives in positioning operators rather than paragraphs, so extraction and re-flow are approximations. Scanned PDFs are worse: pure images with no text layer at all until OCR enters the picture. Still, no other format comes close for final-form document delivery.
